- nrvnrme MACHINE Application filed September 19, 1329. Serial No.393,634.

My invention relates to riveting machines, and especially toconstructions or arrangements of the supporting means for the rivetinghead (or riveting mechanism proper), and cooperative arrangement of theanvil and anvil support, to provide a rearwardly or laterally extendingspace or recess to receive relatively long articles which must extendrearwardly or laterally while the rivets, eyelets, or other fasteners,are set in forward portions of the articles.

One example of such articles requiring a rearward extending space orrecess in the riveting-head supporting means, is garment bags, in whichthe rivets are to be set in a margin of the open or mouth end of the bagwhile the bag itself is disposed generally horizontally, and projectsrearward, or away from the operator and toward the rear of the machine.quite a long distance. The machine is also of course available for manyother classes of articles requiring a large rearward or lateralclearance in the head supporting means. 7

In preferred forms, such clearance space is provided by a separate,generally U-shaped supporting member, secured between the main standard,or supporting column, and the riveting head, and extending in a desiredrearward, angular, or lateral direction, in accordance with the form ordimensions of the articles to be riveted.

The invention furtherprovides a support or magazine for a stack ofarticles, (such for example as garment bags) which may be successivelymoved from the magazine tO I1V6ting position.

The characteristics and advantages of the invention are furthersufficiently explained in connection with the following detaildescription of the accompanying drawings, which show one representativeembodiment. After considering this example, skilled persons willunderstand that many variations may be made without departing from theprinciples disclosed, and I contemplate the employment of any structuresthat are properly within the scopeof the appended claims.

In the drawings:

Fig. 2 is a front elevation.

Fig. 3 is a side elevation of a modified structure or arrangement.

Fig. 4: is a similar view of another modification.

Fig; .5. shows another modification.

Fig. 6 shows still another modified form.

In Figs. 1 and 2, 10 is a standard riveting head, or support for therivet setting mechanism proper, 11. The head or support 10 comprises anupright portion 12 and a horizontal arm 13, at the end of which is therivet setter 14: to cooperate with an anvil 15. Ordinarily, the head 10is secured to a supporting standard or column such as 16 by bolting thebase 17 of the vertical member 12 directly to the top of the column.This evidently provides very little lateral or rearward clearance, orspace in a direction away from the operator, who is stationed in frontof the machine (at the right in Fig. 1), and toward the machine; and itis therefore practically impossible to operate on relatively longarticles which must extend in the stated directions while rivets are setin forward margins thereof, located between the setter 14 and anvil 15.To provide the rearward or other clearance necessary for work of thecharacter indicated, in the specificform of the device shown in Figs. 1and 2, I interpose between the head .10 and column 16 a generally U-shaped head-supporting member 18, comprising an upper arm 19, a lowerarm 20 and a connecting portion, or U-bend 21 connecting the arms. Thebase of the upright member 12 of the head is connected to the front endof the upper arm 19 by bolts or screws 22, and an intermediate portionof the lower arm 20 is connected to the top of the column bybolts 0rscrews 23; The space or bight 24 between arms 19 and 20 provides thenecessary ample rearward clearance for articles of the character abovementioned. In the structure of Figs. 1 and 2, an integral portion 25 ofarm 20 extends forward and upward, and the anvil 15 is securednon-adjustably or adjust ably in the forward end of this arm inproperposition below the rivet setter 14, the position of which is determinedby the standard.- ized dimensions of the head 10. Deep garment bags orother articles which must extend a long way rearward or away from theoperator, are pushed into the space between the rivet setter and anviland into the space or bight 24c, and may be moved laterally as rivetsare set in their forward marginal portions. 7

While the U-piece 18 is here shown as extending rearward, it may extendangularly or laterally, in a generally horizontal direction, toaccommodate wide work-pieces of various characteristics. V

In the preferred forms, as shown in Figs. 1 and 2, and other figureslater referred to, the generally U-shaped supporting structure 18 isseparate from the column 16 and the head 10 and may therefore beinserted be tween any column of suitable height and any ordinary orstandard head such as 10; and when the anvil supporting member such as25 is, as shown in Fig. 1, properly directed or arranged with referenceto the dimensions of the head, the anvil is thereupon properlypositionedin relation to the rivet setter 14.

The separate U-piece provides great facility in assembling completemachines, since it is only necessary to place and secure it between thecolumn and the riveting head, in a desired position, to adapt themachine for any of a. variety of operations, or work pieces of varyingshapes or dimensions.

If desired, the arms 20 and 19 and U- bend 21, or their equivalents, maybe integral with the column and upright 12 of the head 10 and the anvilsupporting member may be also integral, or separate piece and attachedto the column in any convenient way.

Fig. 3 shows a modification in which the anvil supporting member or arm25 extends forward and then upward at 26 and its end portion 27 isturned horizontally reversely or backward toward head 10, thus providinga space at 28 extending forward below the anvil 29 which is secured inthe end of the horizontal member27. This allows for the convenientlocation of one portion of a workpiece, such for example as the marginof one side of the mouth of a garment bag, in the space 28, withoutbending or crumpling, while the margin of the upper portion of the mouthis placed between the rivet setter 14 and the anvil 29 for convenientsetting of rivets in that margin.

This arrangement as well as others also provides a convenient support ormagazine to receive, for example, a stack of garment bags or otherarticles located in the space be r tween support arms 19 and 20. Thespeed of operations is increased by placing such a stack of articles inthe magazine and draw ing forward the uppermost articles successivelyfor the riveting operation. When the articles are wide as well as long(or deep) their laterally extending portions may be supported by tablesplaced at either side of the machine as viewed in Fig. 2.

Fig. 4 shows another modification, in which the arms 19 and 20 of theintermediate supporting structure 18 are sloped rearwardly downward,thus better providing for the proper retention in the magazine of astack of articles, which will naturally tend by gravity to remain inproper position in the magazine, resting against the U-bend 21, whilethe uppermost articles are successlvely moved forward for the rivetingoperation.

The anvil 15 is in this example carried by an diate supporting structuresuch as shown in Fig. 1 has an integral forward extension 35, and theanvil 15 is carried by a separate upright support 36 bolted at 37 to theforward end of the extension 35. The anvil support is curved forward andthen rearward, providing a bight or space at 38 for purposes generallysimilar to those of the space 28 in Fig. 3.

In Fig. 6, the intermediate supporting structure 18 is of simple U-formand the anvil supporting means comprises a forwardly extendinghorizontal member 40 and an upright member 43. The horizontal member 40is bolted to the column 16 at 42 and the stem 43 of the upright memberis bolted to the forward end of arm 40 at 44:. The stem 1-3 of theupright member has at its upper end a U-fo'rmation 45, the bight 46 ofwhich is directed rearward to provide a space for certain portions ofarticles while other portions thereof are riveted, as, for example, inFigs. 3 and 5. The anvil 15 is secured in the upper end of theU-formation.

From the examples given, it is evident that the general objects of theinvention may be attainedby various specific structures and that thesupporting structures, as above explained, may be in two or more parts,to provide ample rearward or lateral clearance or article receivingspace, which is a principal feature of the invention.
